Lotus Elan

Cylinder head breather

PostPost by: type36lotus » Thu Dec 09, 2004 6:26 pm

Many of the metal cages which hold the the water bottle to your bike
frame have holes only on one side. Some have a metal bottom which
you can drill some holes into so you can bolt the cage upright
without having to make a "L" bracket to support it.

Yes, that is what I have for my radiator overflow. I cut the
drinking nipple off, instered a gromet in the hole, then the tube
into the gromet. The bottle cage is screwed down from the bottom.

Go to your local bicycle shop. They carry a wide variety of water

and cages. Looks and works good.

Speaking of catch tanks...I don't like sucking it back into the back
thru the carb either. The tanks I see in racing catalogs look kind
of

big (and expensive) to fit the Elan. I've seen racer's use various
homemade (usually beer) cans. Just wondering what you all use and
where

you put it.

Trouble with using a pretty bottle here in the UK is that as a crankcase
breather system I don't think it is legal..
Hence the stealth approach...
BTW my current Rad over flow bottle is a indian tonic bottle (the car
came without one and this was the only one I could find that fitted!

In 750 clubman racing/hillclimbing/sprinting etc where many of the cars have
to have MOT's, it is legal to have the pipe open and drip onto the
racetrack. However, the bottle solution has been used for years.

The good old crossflow is still widely used and you see many Sylva's etc
with plastic 2pt milk bottles strapped in the engine bay!

However as I don't go racing (yet) in my Stylus I just used a small K&N
filter and vented to atmosphere.

If someone wants an oil breather with filter and valve for a 116E block, I
have some, used spare from my Lotus Seven pre-XF, which I will ship for
the costs of P&P. I can email a picture, if you want.

Vulcan http://www.vulcanengines.com/ has breathers and an aluminium catch
tank, which can be found on their home page.

Remember you cannot use the valve unless the pipe is connected to the inlet
manifold, otherwise it will not work!

Hi Jon,
The issue of crankcase breathers came up in the truimph forum when I
owned a spitfire. In theory apparently the reason car manufacturers
moved from an open breather system to putting the fumes through the
carbs was because the law changed (some of the older cars seemed to put
more nasty stuff out through the breathers than the exhaust).
This was an issue for me at the time as I had dumped the stock SUs in
favour of Webbers, making routing the breather system an issue.
However it seems now that MOT inspectors see so few cars old enough to
have the option of open systems, that they rarely look.
certainly, I just directed onto the road and no one noticed!
Cheers
Tim

There is a nice Lucas water bottle used on later BMC cars. About the same
size as a drink bottle and there is a cage for it. I believe it is still
available.

Yes it was emission laws that got that fixed. I remember seeing cars
blowing oil out of the tube. A lot was a sign of immanent expense. Also
race tracks don't want you blowing oil on the road either.

I found that the only thing that kept the breather hose in the head
was the fact that it is squeezed between the head and the air
cleaner. If the pipe is hanging down into an overflow, what keeps it
from falling out of the head?

There should be a gromet to hold the pipe in the head according to the
spares manual.

The vent to atmosphre pipe also had a tab with a hole to be mounted
to the tramsmission. This fastened the breather pipe to something
rigid.

While I had my engine out and the head off I tapped the breather hole in the head and fitted an hose connector now it can`t fall out or leak and i route it to a bottle in front of the radiator

I found that the only thing that kept the breather hose in the head
was the fact that it is squeezed between the head and the air
cleaner. If the pipe is hanging down into an overflow, what keeps it
from falling out of the head?

However it seems now that MOT inspectors see so few cars old

have the option of open systems, that they rarely look.
certainly, I just directed onto the road and no one noticed!

Straight from the MOT man's mouth (or VOSA man as it now seems to be):

(IANAL, but) he confirmed that there is no requirement to inspect or test
for fumes (or anything else) from any orifice other than the exhaust. The
manufacturers took to positive crankcase ventilation presumably in response
to some C&U reg (about 1964-5 as I remember), but (and HINAL either) "you
would be unlucky to find a copper that would do you" unless the engine is
breathing so heavily that the rings are so knackered the exhaust emissions
test would probably fail too.

So, with an engine in respectable condition, you should have no problem (in
the UK) running to a catch tank (which is only a competition requirement) or
simply venting to somewhere out of the way. Certainly from my experience
of Minis, after they had introduced PCV, they then went on to put an extra
breather in the flywheel housing which had not much more than a Brillo pad
by way of filtering, so I'm not at all sure how stringent the C&U regulation
was.

The other side of all this is the theory that if you use manifold vacuum to
evacuate the crankcase, it assists piston ring sealing, but I have never
been convinced that compared with combustion chamber pressure there would be
much to gain....

Anyway, wife's car now through, my Land Rover is booked in for this
afternoon, and as it has got through the last 5 tests without work, I'm
expecting to have to do something this year! And I really must get around
to having them tested at a better time of year, and preferably more than 2
weeks apart.....

Cheers
